My good friend owns a shop and I"m getting an xcal3 from him next week for my 98 LSC.
I've never used one before...while he says he has "all" software for it, I don't plan at least yet to write my own tunes.
I should have my choice of what I want him to load onto it...
I've got a stock...
A search didn't net me much results...I read that it's the gen 2 tune pulling timing...the gen 1 has a better intake..etc etc.
Can anyone confirm for sure what it is? What i'd need to get my 98 up to par?? How much quicker are the earlier models?
